html - javascript chalanging form elemts array validation -


hi have 1 html form.

<form name="modeladd" ethod="post" class="form label-inline" enctype="multipart/form-data" onsubmit="return check('modeladd');">             <?php  for($i=0;$i<$tot;$i++) { ?>                       <div class="field">                 <label for="connect_msg">connect message </label>                                                                                    <textarea rows="4" cols="50" name="connect_msg[<?php echo getfield($langs[$lan]);?>]" id="connect_msg[]"><?php echo getfield($row[$lan]); ?></textarea>                 </div>                               <div class="field">                 <label for="call_msg">call message :</label>                                                                 <textarea rows="4" cols="50" name="call_msg[<?php echo getfield($langs[$lan]);?>]" id="call_msg"><?php echo getfield($row[$lan]); ?></textarea>                 </div>                  <div class="field">                 <label for="stripline_msg">stripline message :</label>                                                               <textarea rows="4" cols="50" name="stripline_msg[<?php echo getfield($langs[$lan]);?>]" id="stripline_msg"><?php echo getfield($row[$lan]); ?></textarea>                 </div>             <div class="field">                     <label for="cost_msg">cost message :</label>                                                                 <textarea rows="4" cols="50" name="cost_msg[<?php echo getfield($langs[$lan])?>]" id="cost_msg"><?php echo getfield($row[$lan]); ?></textarea>                 </div>                           <?php } ?> <input type="submit" class="btn btn-grey" value="submit"> </form>

here javascript validation 

function check(form) {    var name = new array();    name =document.getelementbyid('connect_msg[]').value;     for(var i=0 ; i<=1; i++)    {        alert(name[i].value);     }    return true; }

i not getting value both connect_msg field array. want validate both field value using javascript pls me

  1. the id cannot have [] symbols. please validate markup: http://validator.w3.org/
  2. the value returned element type string, can't array. can parse string create array.

eg. assuming following outputted markup: 

<textarea id="connect_msg">a,b,c,d,e,f,g</textarea>

you can in javascript:

var getconnectmsg = document.getelementbyid('connect_msg').value; var connectmsgarray = getconnectmsg.split(',');

and connectmsgarray contain ['a','b','c','d','e','f','g'].

you can read more .split() here: https://developer.mozilla.org/en-us/docs/javascript/reference/global_objects/string/split

edit: since textarea in loop, it's more easier retrieve elements using class name attribute, , using jquery immensely.

so html output this:

<textarea class="connect_msg" id="connect_msg1">a,b,c,d,e,f,g</textarea> <textarea class="connect_msg" id="connect_msg2">h,i,j,k,l,m,n</textarea> <textarea class="connect_msg" id="connect_msg3">q,r,s,t,u,v</textarea>  var getconnectmsg = $('.connect_msg'); getconnectmsg.each(function(){     var getvalue = $(this).val();     var connectmsgarray = getvalue.split(','); });

in each iteration of .each(), value of getvalue be:

 a,b,c,d,e,f,g  h,i,j,k,l,m,n  q,r,s,t,u,v

you can form validation set of fields during each iteration.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
